摘要
提出了一种通过对信号的过采样方法,改善频偏估计;通过对同步信号的修改,在不影响定时同步性能的前提下,简化整个系统;通过对AWGN信道和多径衰落信道下的实验仿真结果的分析,可以看出此改进方法能够满足3GPP-LTE系统对小区搜索性能指标。
This paper proposes a method for signal over-sampling to improve the frequency shift estimation.The modification of synchronized signal,can simplify the whole system without affecting the timing synchronization performance.The simulation of AWGN channel and multipath fading channel shows that the improved method can meet the 3GPP-LTE system the search performance indicators.
